Package MagickCore was not found in the pkg-config search path

I was trying to install rmagick and it always asks for PKG_CONFIG_PATH not configured.

This happened multiple times to me, so I'm posting this as an issue and answering myself for anyone else facing same issue.

Solution

  • rmagick gem is not able find PKG_CONFIG_PATH while installing. We need to tell where the path for the ImageMagick exists. It's always better to add in the bash.

    export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.3-7/lib/pkgconfig
